Design of X band low phase noise dielectric resonator oscillator

Microwave dielectric oscillation frequency source uses a small size, light weight, high Q value, inexpensive dielectric resonator (DR) as a resonant unit. It has the advantages of miniaturization, low phase noise, high stability and low cost and had already been widely applied, so the research on microwave dielectric oscillator has also become one of the focus of today´s microwave integrated circuits. This paper describes the working principle and design method of the DRO. Through reading lots of literature on DROs, the author has deeply knows about the theory of DROs and designs a circuit with both HFSS and ADS simulation software.
